[0022] It should be noted that the suspension seat 1 provides suspension support for the sampler, making it easier for the extraction tube 12 to sample the sewage.

[0023] The sampling tube 2 is internally slidably connected with a piston block 11, and the top end of the sampling tube 2 is threadedly connected with a screw shaft 10 rotatably connected to the piston block 11. A dual-axis motor 5 is installed on the inner wall of the suspension seat 1, and a transmission assembly is connected between one end of the dual-axis motor 5 and the top end of the screw shaft 10. The transmission assembly includes a driven gear 3 rotatably connected to the top end of the sampling tube 2 and a driving gear 4 fixedly connected to the output shaft at one end of the dual-axis motor 5. The driving gear 4 and the driven gear 3 are meshed with each other. A sliding opening is provided at the center of the driven gear 3, and a limit slider is fixedly connected to the inner wall of the sliding opening. The screw shaft 10 passes through the sliding opening and extends to the top of the driven gear 3. A sliding groove 1001 is provided on the surface of the screw shaft 10, and the sliding groove 1001 is slidably connected to the limit slider;

[0024] It should be noted that: the dual-axis motor 5 drives the driving gear 4 to rotate, and then drives the driven gear 3 to rotate, and the driven gear 3 drives the screw shaft 10 to rotate, so that the screw shaft 10 drives the piston block 11 to move upward, thereby realizing the sewage extraction function;

[0025] It is worth noting that the limiting slider cooperates with the slide groove 1001 so that the driven gear 3 drives the screw shaft 10 to rotate, while ensuring that the screw shaft 10 can move up and down.

[0026] The bottom end of the suspension seat 1 is provided with a screw propulsion assembly for driving the suspension seat 1 to move, and the screw propulsion assembly includes a driving housing 7 fixedly connected to the bottom end of the suspension seat, a rotating shaft 9 rotatably connected to the inner wall of the driving housing 7, an impeller 8 circumferentially distributed on the surface of the rotating shaft 9, and a driven bevel gear 15 fixedly connected to one end of the rotating shaft 9, and the output shaft at the other end of the dual-axis motor 5 extends to the inner side of the driving housing 7 and is fixedly connected to a driving bevel gear 14 meshing with the driven bevel gear 15;

The driving bevel gear 14 drives the driven bevel gear 15 to rotate, and then drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the impeller 8 to rotate to achieve a spiral propulsion effect, and then drives the suspension seat 1 to move on the water surface. At the same time, the driving gear 4 drives the driven gear 3 to rotate, and then drives the screw shaft 10 to rotate, so that the screw shaft 10 drives the piston block 11 to move upward, and the sewage can be extracted into the sampling tube 2.
